SPENCER MICHELS: Sergay Brin thinks the ultimate search engine would be something like the computer named Hal in the movie 2001: A Space Odyssey.
SERGEY BRIN: Hal could... had a lot of information, could piece it together, could rationalize it. Now, hopefully, it would never... it would never have a bug like Hal did where he killed the occupants of the space ship. But that's what we're striving for, and I think we've made it a part of the way there.
